JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent N0.320,151, dated June 16,1885.

Application filed January 24, 1885.

lb all whom it may concern.-

Be it known-that I, PHILIP MEDART, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Self-Oiling Boxes for Journals; and I do hereby declare the following to be a full and accurate description of same, reference being had to the annexed drawings and letters of reference marked thereon as a part of this specification.

The object of my invention is to construct an oil-box with a wick that will feed the oil on thejournal in proportion as the journal is hot or cool.

My invention relates to self-oiling journal boxes.

In consists, first, in providing a journalbox with a tight oil-box or receptacle for the oil situated above the journal to be oiled, said oil-box being provided with a wick passing over the end or side of the box and down through an opening in the box to the top of the journal, to carry the oil over the end or side of the box by siphonic action to the top of the journal below; second, it also consists in providing the under side of the box with a groove running parallel with the journal to receive the wick, so that the heat of the journal can act upon the wick and cause the oil to flow as it is needed.

Figure 1 in the drawings is a perspective view of my box with a part of the lid out away to show the wick passing over the end of the box. Fig. 2 is a longitudinal section of my oil-box, showing the lid L, the oil-box B, the wick W, the groove G, and openings at the ends of the oil-box, o 0, through which the wick passes to the journal J. Fig. 3 is an under side view of the lid of the box, showing depressions e e on the under side of the lid at each end, so as to allow the wick to pass over the end of the oil-box. Fig. 4 is a transverse section of the box and lid on the line 4 4 in Fig. 2, and shows the depressions e on the lid, the opening for the wick to pass down, and the groove at the bottom of the box.

The oil-box B is a plain ordinary box cast on the upper part of the journal-box B, and has no aperture through which the oil can es- (No model.)

cape. It is also provided at each end with openings 0 0, which reach from the top of the oil-box B to the bottom of the upper half of the journal-box B, and is made large enough to permit the wick to pass down to the bottom of the upper half of the journalbox B. This upper half of the journal-box may be termed the cap of the journal-box. The lower surface of this upper half of the journal-box B has a groove, G, running along the internal bearing of the same and parallel with the journal, and made large enough to receive and hold the wick \V, which is a wick of any porous substance, and which runs along the groove G, up the openings 0 0, over the ends of the oil-box B, and rests in the bottom of the oil-box B, where it is saturated with oil in the box. Now, when the journal J be comes warm by friction it will heat the wick W and warm the oil in it, and cause the oil to fiow from the wick along the groove of the journal-box and cause it to draw the oil out of the oil-box B by siphonic action. Thus in proportion as the journal is heated the oil will flow from the wick and draw its supply from the oil-box B over the ends of the same, and will not flow until it is warmed up by the heat of the journal, if the right consistency of oil is used, which can easily be ascertained by the person using the journal-box. By running the wick parallel with the journal the journal will be oiled the whole length of the bearing.

I know there have been wicks used to oil journals before 5 therefore I do not claim wicks in themselves as new for oiling journals; but

WVhat I do claim, and for which I ask Letters Patent to be granted me, is

1. In an oil-box, the wick W, passing along a groove, G, in the bottom of the upper half of the journal-box B, up through the openings 0 0, and over the edges of the oil-box B and into the same, operating to draw the oil out of the oil-box B and distribute it along the groove G.

2. The combination of the box B, located above the shaft J, and provided with the vertical passages 0 at its ends and the groove G in its under side, with the cover L, having the recesses e in its ends, and the endless wick \V, In witness whereof I have hereunto set my which passes through both the box and the hand on this 17th day of January, 1885, at St. groove, substantially as set forth. Louis, Missouri.

3. In an oiHoox, the lid L, provided with PHILIP MEDART. 5 depressions e e on its under side at or near the Attest:

ends to allow a free passage of the wick be- WM. M. ECCLES, tween the lid and the edge of the oil-box. I A. A.-PAXSON.
